TONCUE-SUPPORT,l

SPECIFICATION forming part of Letters Patent No. 503,205, dated August15, 1893. Application filed December 10, 1892. Serial No. 454,790. (Nomodel.)

To all whom it may concer-n:

Beit known that I, DON C. EMERsoN,a citizen of the United-States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improvements in Tongue- Supports; and Ido hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in tonguesupporters by means of which a supporter is provided being simple inconstruction, durable and cheap in first cost.

More particularly my invention relates to that class of tonguesupporters, which are designed to be attached to the tongue of a reaper,mower and suchlile in such position thereon that the weight of themachine and tongue will be taken oft' from the horses necks and willequalize or resist violent movements of the tongue occasioned by themachine running over rough surfaces and will also assist in overcomingany tendency toward side draft of such machine.

My invention consists essentially of a vertically, adjustable barprovided with a suitable ground wheel and of a substantialframe workwithin which the vertically adjustable bar is carried and within whichthe same is adjusted by being carried through suitable vertical openingstherein and of a spiral spring carried around the bar and Within thesaid frame Work within Which itis confined and J of an adjustable opencollar carried upon the said bar and of a suitable bolt carried in theopenings in the perforated ears of the said collar which clamps it uponthe vertically adjustable bar and facilitates the easy adjustment of thesaid collar upon the bar to provide for different degrees of compressionof the said spring to accommodate it to dierences of weight to be borne.

That my invention may be more fully understood, reference is had to theaccompanying drawings, in Which--- Figure 1 shows my invention completeand attached to a tongue. Fig. 2 is a detailed View of the frame workcarrying the vertically adjustable bar. Fig. 3 is a detailed viewshowing the means of attaching the collar to the Vertical bar by meansof the bolt.

In the drawings A, A', A relate to the parts of an open framework, whichare all integral with the base A, which is attached to the tongue bymeans of suitable bolts, the said parts constituting a frame Work and isprovided with a vertical opening in the bottom and top parts. `B, is abar carried within the vertical openings in the said frame work, and isbifurcated at its lower portion and bears between its respective partsC, the wheel D, which is designed to bear upon the ground.

e is an open collar provided with outwardly tending perforated earsthrough which is carried the bolt e and is designed to be carried aroundand clamped upon bar B.

B, is a spiral spring carried around and upon the said bar B and is heldwithin the open frame work bearing at its lower portion upon the collare, and at its upper portion against the upper part of the open framework.

In operation for the purpose designed, the complete device being rstattached in the manner shown, and the several parts of the devicecarried in their relative positions and adjustment, it will be seen thatwhen from any cause the Weight of the machine is thrown upon the forwardside of the axle the tendency to bear down upon the horses necks will beovercome by the resistance of the spring Y E, acting through the severalparts of the device, but that the resistance will not be positive orabrupt because of the compressibility of the said spring; and it willfurther be seen that any tendency toward side motion will be overcome byresistance occasioned by .the contact of the wheel D with the ground.

As previously explained dierent degrees of compression or rather ofcompressibility of the spring may be had by the simple adjustment of thecollar provided.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is
